Parents are having to pay more than £100,000 extra for a home if they want to send their children to a good state school in Surrey, new figures show.

Land Registry housing data has revealed house prices change dramatically depending on the success of nearby state schools.

Homes near schools within the top 20% for GCSE results in the county were £102,000 pricier than those in the bottom 20%.

And parents will have to dig deep if they want a property near one of the desirable institutions, as house prices average at £432,000.

In comparison, house prices within the catchment area of some of the poorer performing state schools cost on average £329,886.

A spokesperson for Savills estate agents said: "Research undertaken last year showed that, in some cases, purchasers were prepared to pay a premium of 22% for homes within the catchment area of an Ofsted-categorised 'outstanding' school.

"The demand is such that the catchment area around the some of the most popular schools has shrunk to barely 600 metres."

'Weigh up what you can afford'

The spokesperson also confirmed Savills offices in Surrey were "seeing an influx of buyers in the family house market moving out of London, not only to achieve more house for their money but also to increase their choice of educational establishment".

But they added that average property prices near railway stations could be even higher than those in the catchment areas of good performing state schools.

"The average 2013 value of property sold within the catchment area of George Abbot, an Ofsted 'outstanding' state school [in Guildford] and academically deemed very strong by the Good Schools Guide, is less than property located closer to Guildford and London Road main line stations," the spokesperson said.

Mother-of-two Caron Shaw, who lives in Copperfield Rise, Addlestone, said: "We moved into our house when I was pregnant with my first child and going to a more desirable school wasn't something I really looked at.

"But now my children are almost finishing primary school, I must admit that I have been thinking about what secondary school they'll go to.

"Catchment areas do play a part when buying a house, but you have to weigh up what you can afford.

"Other things play a factor in house prices too, but I'm not surprised that houses are more expensive near desirable schools, as parents will want their child to go to a good school."

Postcodes

The steep climb in property prices can often be seen between schools located very close to each other.

For example, Thamesmead School in Shepperton is one of the best performing state schools in the area, with 74% of its students achieving five GCSEs at A* to C.

Houses in the same postcode sector will set you back an average of £542,000.

Just four miles away is The Matthew Arnold School in Staines, which achieved only 42% five A* to C grades last year and around which average property prices are more than £200,000 cheaper, at £329,886.
